The above chemical equation shows that when 4 moles of nitric acid (HNO3) react with 5 moles of hydrogen sulfide (H2S), it will form 4 moles of sulfuric acid (H2SO4), 4 moles of nitric oxide (NO), and 2 moles of water (H2O).
- Reaction conditions:
The specific conditions for this reaction may vary based on factors such as temperature, pressure, reaction environment, etc. However, this reaction is usually conducted at standard temperature and pressure.
- Reaction process:
In this reaction, nitric acid (HNO3) reacts with hydrogen sulfide (H2S) to form sulfuric acid (H2SO4), nitric oxide (NO), and water (H2O). This is also known as a redox reaction, as nitric acid (HNO3) is reduced to nitric oxide (NO) and hydrogen sulfide (H2S) is oxidized to sulfuric acid (H2SO4).
- Phenomena occur:
When the reaction occurs, you can see a change in color. The reaction environment will also release blue nitric oxide (NO) gas.
